Description

[Detailed description of the invention] This invention relates to a hot air heater equipped with a cooling unit at the top, which increases the strength of the upper cooling unit against the weight, and also improves the strength of the upper cooling unit with respect to the weight. The purpose is to block thermal effects and improve ease of assembly and maintenance.

Conventional warm air heaters of this type use the exterior itself as a structure to provide strength, making installation, maintenance, and disassembly difficult.

Moreover, in this type of hot air heater, the center of gravity was at the top due to the cooling unit located at the top, making it insufficient in terms of strength.

The present invention is intended to eliminate such drawbacks, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 5, in this embodiment, a right inner plate 3 and a left inner plate 4 (right and left facing plates 3
, 4 may be replaced with a support post).

Further, the right side plate 1 and the left side plate 2 are screwed to the top plate 5°6 from the inside.

A cooling outlet grill 7 and an outlet lid 8 are attached between the top plates 5 and 6.

In addition, as shown in FIG. 4, the right side plate 1, the left side plate 2, the top plate 5,
The top plate 6 and the outlet lid 8 are partially assembled as an outer box unit, and are screwed to both sides of the pedestal 9 so that they can be attached and detached at the time of maintenance.

A right inner plate 3, a left inner plate 4, and a left heat shield plate 10 are attached to the folded portion 9a of this mount 9, and a right-facing plate 3, a left-facing plate 4
A cooling unit fixing fitting 11 is fixed to the
1 is an L fitting 1 provided on the board 13 of the cooling unit 12.
4 are screwed together in a corresponding manner.

□On the other hand, the heating burner section 1 attached to the partition plate 29
A propeller fan 18 driven by a hot air fan motor 17 blows wind onto the heat exchanger 16 fixed to the heat exchanger 5 , and this warm air is blown out from a hot air outlet 19 .

A filter 2 such as a lath net is installed at the suction port of the propeller fan 18.
Equipped with 0.

There is an operation part 21 on the right side of the hot air outlet 19, and the lower part is covered with a front plate 22.

Further, the height of the legs 23 attached to the pedestal 9 can be varied on the pedestal 24 for horizontal adjustment.

On the other hand, the air blown to the cooling unit 12 is sucked in from the cooling suction port 27 by the cross fan 26 driven by the cooling motor 25, and the cold air is blown out from the cooling outlet grille 7.

The heat radiated from the heating heat exchanger 16 to the cooling unit 12 is shielded by the left heat shield plate 10 and the upper heat plate 28, but this is not sufficient to prevent thermal influence on the cooling unit 12.

Therefore, in this embodiment, the cooling unit fixing fittings 11 and L
By appropriately setting the height of the metal fitting 14, an effective heat insulation distance can be maintained.

In particular, the drain pan 30 for cooling is often made of foamed synthetic resin.

This thermal insulation is especially necessary.

Note that 31 is a rear plate.

The present invention has been stolen as described above, and has the following effects.

(1) It is strong because the inner plate supports the load of the upper cooling unit.

(2) By providing a heat shield plate between the cooling unit and the heating section, a sufficient insulation distance can be easily maintained, and the distance can also be set freely.

Furthermore, by communicating this insulating space with outside air, natural circulation cooling is performed, and the thermal influence on the cooling unit can be extremely reduced.

(3) Since the inner plate is used as a structure and supports the cooling unit with strength, the exterior can use a thin plate that only functions as a cosmetic case, and there are fewer screwed parts, so the design is improved. The effect will be higher.

Furthermore, it is convenient if the exterior is made into a unit as shown in FIG. 4, for example, because it can be easily removed for maintenance.
